In GH-15647, the `array_filter` function was changed to throw a
`ValueError` exception when the `$mode` parameter receives an
invalid.
Additionally, it declares a new `ARRAY_FILTER_USE_VALUE`, assigned
(`int 1`) to it.
This changes the default value of the `array_filter` function's
`$mode` parameter to use the new constant, changing it from
`int $mode = 0` to `int $mode = ARRAY_FILTER_USE_KEY)`.
Closes GH-21100.
The aim of this PR is twofold:
- Reduce the number of highly similar TMP|VAR handlers
- Avoid ZVAL_DEREF in most of these cases
This is achieved by guaranteeing that all zend_compile_expr() calls, as well as
all other compile calls with BP_VAR_{R,IS}, will result in a TMP variable. This
implies that the result will not contain an IS_INDIRECT or IS_REFERENCE value,
which was mostly already the case, with two exceptions:
- Calls to return-by-reference functions. Because return-by-reference functions
are quite rare, this is solved by delegating the DEREF to the RETURN_BY_REF
handler, which will examine the stack to check whether the caller expects a
VAR or TMP to understand whether the DEREF is needed. Internal functions will
also need to adjust by calling the zend_return_unwrap_ref() function.
- By-reference assignments, including both $a = &$b, as well as $a = [&$b]. When
the result of these expressions is used in a BP_VAR_R context, the reference
is unwrapped via a ZEND_QM_ASSIGN opcode beforehand. This is exceptionally
rare.
Closes GH-20628
Prior to this patch there was a common read handler, and it relied on
the dom class set in the intern document. However, Dom\Implementation
allows creating DTDs unassociated with a document, so we can't rely on
an intern document and the check fails. This causes the ZVAL_NULL() path
to be taken.
To solve this, just split the handler.
Closes GH-21082.
* Fix regression with header removing removing whole prefixes
The header removal code looked for the colon for key-value at the wrong
place, so it would overzealously remove headers. Tweak that condition,
and make the alternative condition only active if it's set (with the
remove prefix op case).
Fixes GH-21018.
* avoid reading past the actual length
* Rename variable to be more clear
This is a follow-up of 668606816f
(GH-21001).
The SPL extension is no longer needed to be listed among dependencies.
The https://bugs.php.net/53141 is tested in
ext/session/tests/bug53141.phpt.
Additionally:
- Added missing inclusion guards to Zend/zend_autoload.h
The primary motivation for this change is that this sort of functionality should reside in core and not in an extension.
The reason being is that this causes issues in regard to extension dependencies and resolution,
something that prevents GH-14544.
* zend_compile: Fix handling of PFA syntax in array_map() optimization
PFA is not implemented and the syntax is rejected at compile-time, thus it was
assumed the assertion would be unreachable. However the check for PFA syntax
happens after compiling special functions, making it reachable. Fix this by
gracefully returning FAILURE which will then correctly emit the error during
the compilation of the normal call.

* zend_compile: Fix array_map() optimization for dynamic function names
Fixesphp/php-src#20990.
* zend_compile: Adjust array_map() optimization after review feedback
In a lot of places the return value is not checked, and when the
function fails the code continues execution. However, this means that
operations on the stack fail and will cause memory leaks on the objects
that weren't pushed.
We also notice an inconsistency in how these failures are handled.
For example, in one place we explicitly have a fatal error
`php_error_docref(NULL, E_ERROR, "Memory allocation failure");`
but this is the only place to do so.
Closes GH-20957.
This test still fails on i386 Windows with "Allowed memory size of %d bytes
exhausted" because the output buffer grows too big. My first intuition was to
add a chunk_size to ob_start, but this won't work if the output buffer is
flushed deep into the call stack, causing a premature or just a second stack
limit error. So, reduce the stack size in an attempt to produce less output.
